2019年甘肃省克山病病情现况调查

A survey on the current situation of Keshan disease in Gansu Province in 2019

目的掌握甘肃省克山病病区人群病情现状及消长趋势, 为克山病重点防控提供科学依据。方法 2019年, 采用横断面调查方法, 在甘肃省28个克山病病区县(区)的所有病区乡(镇)开展病情监测, 收集监测县(区)所辖病区情况, 在全乡(镇)范围内, 以病区村为单位, 由村医线索调查疑似心肌病病例。按照《克山病诊断》(WS/T 210-2011)对疑似病例进行诊断。结果甘肃省8个病区县(区)无克山病病例检出, 其余20个县(区)均有慢型、潜在型克山病病例检出, 未发现急型、亚急型克山病病例;现有克山病病例668例, 其中慢型克山病509例、潜在型克山病159例;发现1例新发慢型克山病病例, 年发病率为0.10/万(1/96 449)。慢型、潜在型克山病病例男、女性别比分别为1.33 ∶ 1.00(291 ∶ 218)、1.01 ∶ 1.00(80 ∶ 79);慢型、潜在型克山病病例均以> 50 ~ 60岁年龄组为主, 分别占36.94%(188/509)和42.14%(67/159), 其次是> 60 ~ 70岁年龄组, 分别占36.15%(184/509)和25.79%(41/159)。结论甘肃省克山病病情处于平稳低发势态, 但仍有新发病例出现, 应保持病情监测的持续性。

Objective To learn about the current situation and growth and decline trend of Keshan disease in Gansu Province,so as to provide scientific basis for key prevention and control of Keshan disease.Methods In 2019,the cross-sectional survey method was used to carry out case search in all diseased townships(towns)in 28 diseased counties(districts)of Gansu Province.The situation data of the disease areas were collected under the jurisdiction of counties(districts),and suspected cardiomyopathy cases were investigated by village doctors in the whole township(town)with the village as the unit.Suspected cases were diagnosed according to"Diagnosis of Keshan Disease"(WS/T 210-2011).Results No Keshan disease cases were detected in the disease affected 8 counties(districts)of Gansu Province,and chronic and latent Keshan disease cases were detected in the remaining 20 counties(districts),and no cases of acute or subacute Keshan disease were found.There were 668 cases of Keshan disease,including 509 cases of chronic Keshan disease,159 cases of latent Keshan disease;and 1 new case of chronic Keshan disease was found,the annual incidence rate was 0.10/10000(1/96449).The specific ratios of male and female patients were 1.33∶1.00(291∶218)and 1.01∶1.00(80∶79)in chronic and latent Keshan disease;the age of chronic and latent Keshan disease was mainly>50-60 years old,accounting for 36.94%(188/509)and 42.14%(67/159),respectively,followed by the>60-70 years old,accounting for 36.15%(184/509)and 25.79%(41/159),respectively.Conclusion Keshan disease is in a stable low incidence situation in Gansu Province,but there are still new cases,so the continuity of disease monitoring should be maintained.
